CAN-BODYMAKING MACHINE.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed September 13, 1909. Serial No. 517,362.

To all whom it may concern Be it known that I, FRANK RUDOLPHI, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can-BodyMaking Machines, of which the following is a specification.

M invention relates to improvements in can ody making machines, 1111(1'111018 particularly to the part or mechanism of such machines which solders the side seam of the can body after it is formed up, from the fiat blank.

. In can body making machines heretofore generally in use, after thefiat blank has been formed up into a. can body of cylindrica-l or other shape, it is ordinarily pushed forward off of the can body former orn onto a soldering horn, the inner end of which is connected directly to the end body of the former horn, the soldering horn serving to support and guide the can bodies in cooperative relation .with the flux applying, solder applying and solder sweating de vices as they are pushed along said horn by an endless conveyer chain or other conveyor device. And while the expansible body former horn around which the can body blank is formed into a can body serves to size the can body from the interior so that the can bodies are produced of. approximately uniform interior diameter, the can bodies necessarily fit loosely on the soldering horn, which is usually of skeleton form, the operation of soldering the side scam, the can bodies are neither-anternally nor externally sized nor shaped,

or held and maintained of the precise shape, size and diameter necessary to cause them to always uniformly and tightly fit within the flan es of the can heads, although in the motion manufacture of sheet metal cans, it is of the greatest importance that the can bodies should fit with extreme accuracy and tightness within the flanges of the can heads in order to insure perfect and hermetically tight soldered joints and with a minimum amount of solder.

dering horn which fits inside the can bodies, and along which the can bodies are slipped during the soldering operation also tends to mar, in ure or scrape off the lacquer or other And, moreover, the solprotective coating vihich may be applied to the sheets or blanks from which the can bodies are formed. And in the machines heretofore in use, as the can bodies neces-v sarily fit loosely on the soldering horn in order to enable them to he slipped or pushed; alon it, if it is attempted to apply the solder to the lock side seam of the can body by means of a longitudinally arranged roller revolving in molten solder in order to more effectually apply the solder to the seam and:

sweat it therein and economize theamount of solder required, great difliculty is eat-Hv perienced 1n practical operation in prevent,

,ing the can bodies, or some of them, turning slightly. on the soldering horn under the action of the transversely rotating solder applying roller, and thus causin the side seam of the can body to improper y register and contact with the solder applying roller.

The object of my invention 1s to provide a canbody making machine in which the can bodies may be sized from the inside during the body forming operati'on as hereto? fore, and also sized from the exterior during the side seam soldering operation, thus insuring the production of can bodies of uniform exterior diameter or size, so as ,to properly, snugly and tightly fit within the flanges of the can heads as required, and in which also the soldering of the side seam. of the can body may be performed without in any way man-ing either the interior or exterior surface of the can body, or any,

lacquer or protective or decorative coating applied either to the interior or exterior surface thereof, and in which also each and every can body will be accurately presented and firmly held with its side seam in proper cotiperative registration and contact with the solder applying roller or other solder applying or sweat-ing device.

My invention consists in the means I employ to practically accomplish the above object or result. That is to say, it consistsin a can body making machine comprising in coiiperative combination, an expansible, or internal sizing, body former horn, a solder applying and sweating device, preferably a longitudinally arranged roller revolving in a. molten solder vessel, and a can body carricr, preferably an endless flexible carrier or chain, furnished with a series of opening Rad closing, external, sizing can bod holders or clamps to which the can be ies are delivered directly from the body former horn, and by which the can bodiesare con- "veyed and held and maintained externally sized and shaped While being operated upon by the solder applying and sweating device, and the side seam of each can body accurately prese'nted'to such solder applying and sweating device. As each can body is thus externally gripped in a traveling can body holder with its side seam in contact with the solder I applying roller, the rotating solder apply "-16" seam of the can and thus e dering with a minimum amount of solder without producing any tendency for the can device. And as the can body dering operation has along any horn,

body to axially turn or get its side seam out of register withthe solderin or sweating (luring the sol-' no sliding movement the lacquer or other coating on the inside of the can. body cannot be injured, broken or disturbed, and as the can body is externally clamped, firmly compressed, shaped and sized during the solder ln'g operation, there is no possibility of any movement of one member of the scam in respect to the other and consequent defective "SOld8Ilng, and the finished can bodies are thus also for the same reason uniformly produced of the same externaldiaineter or size, so that they will each and all properly and very tightly fit the flanges of the die-made can heads. The external sizing can body holders or clamps are preferably held closed a by stationary tracks or rails with which the operating 3.1: 18 of the clamps engage as they are conveyed along by the earner upon which they are mounted. Stationary cams are al so'preferably employed for opening 1 andclosing the external sizing can body holders'or clamps. The can body former horn is furnished with a short extension for supporting each can body in turn in posi tion to be grasped by the can body holders 'or clamps of the soldering mechanism.

My'invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

The body forming mechanism of my can body making machine may be of any s1iitable kind or construction known to those skilled in the art. It should, however, have an eiqmnsible or internally sizing can bod former horn so that the can bodies will be sized from the inside and thus brought to approximate uniform size or diameter innternally at the time the hooks or edge folds of the lock together. mechanism The body former which I prefer to use is preferably eonor clamp by which it is conveyed formers C seam are bumped or compressed,

structed substantially in accordance with the specification and drawings' of my Patent N 0. 956,180.

In the accompanying drawing forming a part of this specification, I have only shown that portion of the body former mechanism which is directly connected or related to my present improvement, as the other portions of said body forming mechanism are not necessary for a full understanding and explanation' of my invention;

In said drawing, Figures 1 and 2 taken together are a side elevation, partly in vertical. section, embodying my invention, the front portion of the body forming mechanism being broken away or om itted, as my invention has no particular relation thereto. Fig. 3 is a detail plan View of the portion of the machine shown in Fig. 2. Fig. 4C is a rear end elevation. Fig. 5 is a vertical cross section on line 55 of Fig. 1. Fig. 6 is a vertical cross section on line 6-6 of Fig. 1. Fig. 7 is a detail plan view showing the body blank carrier or feed device, the body former horn and certain connecting parts. Fig. 8 is a detail, partial, horizontal section on line 8-8 of Fig. 1, showing certain parts in plan i i ig. 9 is a detail plan View of one of they can body clamps or holders on the can body carrier. Fig. 10 is a detail elevation of one of said can body clamps orholders.

In said drawing, A represents the frame, B the internal, sizing or expansible body former horn, G 0 body formers for wrapping the flat blank around said horn, D a reciprocating body blank conveyor for conveying the body blanks first to the hookformers or edge folding devices E E, and then'to the body former horn B and body and bumper or seam squeezer E said body blank conveyer being also provided with can body ejectors or fin ers d for pushing the formed can body off 0 the former 18 onto the short extension B thereof, which supports each can body inposition to begrasped by the external, sizing can body clamps or holders F of the side. seam. soldering'mechanism.

In actual practice it is found that the hooked parts forming the lock seam are not always sufliciently and uniformly swaged together so as to prevent relative movement thereof either of the entire hooked parts or portions of the same, during the subsequent handling of the formed body, and when this happens the bodynaturally expands and in machines using a-horn for supporting the bodies during the soldering and sweating operations and ordinary chain pushers, there is nothing to restore the bodies to their original or correct size, and the horn tends to increase the size. By usingian eagpanding, sizing body former horn onllie interior of the can body, I provide bodles which cannot body i I position,

, clamp the, can the-hiwer loop 1 rhllelf'of' uniform be too small, and if the seams are properly bumped, are of permanent and correct size, and'hy using and subsequently operating external sizing clamps which hold the bodies to a umform size until. the solder is set, I provide means whereby can bodies, if too large when presented to the clamps, are restored to their proper size.

The body former horn B, body formers C, blank convcyer D, can body ejector a, hook formers E and bumper E may be of any suitable kind or construction. but are preferably constructed substantially in accordance with the specification and drawingsiof my said patent above mentioned; Reference is made to the patent for a more full description of said parts.

The externally sizing can bod y holders or clamps F each comprise a pair of hinged, segmental clamp members, hingedtogether at f and adapted to externally grasp, compress, shape, and size the can body, each pair of clamps leavin onlyia small segment 1 of. the can bed Xa jacent to the lock side seam mithereo exposed for contacting with the solder applying and sweating roller 11. The opening and closing external can body clamps F are preferably mounted on an endless flexible can body carrier G, preferably a linkchain, with the clamps F preferably on each alternate link of the chain carrier. The endless carrier G is preferably mounted on upright ulleys or sprocket wheels Gr G. The en less flexible carrier or chain G is guided and sup orted between the pul leys or wheels G 2 by tracks or rails G the carrier having anti-friction rollers or wheels g to travel upon said rails. Each hinged member of the can body holder or F is provided with an operating arm f, preferably furnished with an anti-friction roller f whichengages a track or rail Ffor holding the clam member in its closed and with trac s or rails f against which 'said arms ride whentbe clamp members are open, and stationary cams F are provided, which engage with the operating arms of said cam members to close the same upon the can body, and further stationary cams F are provided to automatically open the can body'holder or clamp to discharge the soldered can body from the machine.

' The solder applyim roller H is longitudinallycarranged with its axis parallel to body carrier. Grand directly below Tlie solder applying [roller H ispreferably :irmnersed for-the ma or portion of its drlmet er' 1n the molten solder Y in the solder pot or: vessel 11. Said solder applying roller ..is preferably a smooth, cylindrical diameter from end to end. raltisjournaled in suitable bearings h on the lramefof; the machine and is continuously rotated. The solder in the pot or vessel H oithe endless flexible carrier.

is kept in a. molten condition by a suitable furnace or heater H K is a flux applying roller mounted directly beneath the extension B of the body former born 15. It is mounted on the arm K of an adjustable lever K having a weight K for holding the roller in contact with the side seam of the can, body as the can body is pushed along the horn extension B of the body former horn B by the can body ejector d of the body forming mechanism. The flux applying roller K is partially immersed in the liquid flux contained in the flux trough or vessel K". The ilux applying roller is rotated by frictional contact with the can body as a can body is pushed along its support 13.

The can body ejector (Z, as it discharges the formed can body from the body former born B, operates to push the can body into position on, the horn extension B directly under the cam F? which operates to close the externally sizing can body holders or. clamps F, so that'as said holders or clamps close, they firmly grip the can body and externally clamp or size it'and hold it with great firmness so that the can body cannot turn in the clamp or holder F when its side seam is presented to the rotating solder applying and sweating roller H. The can body conveyer -D and can body ejector d thereon may be reciprocated by a-ny suitable mechanism, preferably by that shown and described in my said'pending application.

The endless flexible can body carrier G is preferably driven continuously.
